UNITED STATES PATENTS 2,901,054 8/1959 Larson 182/118 1 Claim, 8 DrawingFigures vigil 1 I I 'PATENIEU wt 1 0 ms HOME SCAFFOLD This inventionrelates to home construction and maintenance, more particularly toscaffolds.

A principal object of this invention is to provide a home scaffold inone hinged unit that opens from its flat storage configuration to anoperative position in which two vertically standing members support aplatform. The platform comprises two floor members in a telescopingmanner for adjusting the distance between the vertical supports. Bracessecure the scaffold in either the collapsed or extended platformposition.

Another object of this invention is to provide a home scaffold that islight, strong, durable and safe.

These and other objects will be readily evident upon a study of thefollowing specification and the accompanying drawing wherein:

FIG. 1 is a front elevation view in the operative position.

FIG. 2 is an end elevation view of FIG. 1.

FIG. 3 is a bottom view of FIG. 1.

FIG. 4 is a view of the knee brace lock.

FIG. 5 is a plan view of the folded scaffold.

FIG. 6 is a fragmentary section elevation view showing a paint trayadapted for attachment to a rung on the vertical members.

FIG. 7 is a fragmentary enlarged elevation view of the telescoping deck.

FIG. 8 is a front elevation view of the scaffold indicating the extendedposition in dot-dash outline.

Referring to the figures, the scaffold 10 comprises a working platform11 spindling at each end a vertical support structure 12 at pins 13.

To steady the scaffold a pair of diagonal braces 14 extend fromspindling pins 15 in structure 12 to locking pins 16 on platform 11. Toaid in storage, braces 14 are made in a pair of members hinged at pins17.

The lower end of braces 14 are provided with slotted openings 18 whichengage and seat on pins 16.

Platform 11 comprises two floor members 19 and 20, ribbed and fitted tobe slid, one in the other, allowing the scaffold to be lengthened. Oneor more additional pins 16 as for example, pin 16A, then serve to securestructure 12.

Articles used in home construction, repair or maintenance may beattached in various ways to the scaffold. By example, a paint tray 21 isfitted with a bracket 22 for support from a rung 23 in structure 12.I-Iooks 24 may be attached for tools. Another hook may be used to hangthe scaffold in storage against a wall. Also a carrying handle 25 may beattached.

Folded flat, as in FIG. 5, the scaffold becomes a long platform that canbe supported between two ladders for larger jobs around the house.

To prevent marring finished floor surfaces in the house, protective pads26 are attached to the four verticals in structures 12.

What I claim is:

l. A portable, extendable, and collapsible scaffold device comprising:

a pair of one-piece vertical support members, each said member havingenlarged portions at the top and bottom ends thereof;

a horizontal platform pivotally connected to each said vertical supportmember at a point approximately midway between said enlarged portions,said platform comprising a plurality of ribbed platform members adaptedto be connected to each other in a telescoping manner;

and a pair of foldable diagonal braces rspectively connected from saidplatform to the top enlarged portion of one of said vertical supportmembers, whereby said braces serve in their unfolded position to bothsteady said scaffold device and reduce the possibility of a useraccidentally stepping off of the platform yet in their folded positionpermit the scaffold device to be collapsed to a rigid and substantiallyplanar configuration for storage or for use as an extended platformbetween a pair of ladders or the like.

1. A portable, extendable, and collapsible scaffold device comprising: APAIR OF ONE-PIECE VERTICAL SUPPORT MEMBERS, EACH SAID MEMBER HAVINGENLARGED PORTIONS AT THE TOP AND BOTTOM ENDS THEREOF; A HORIZONTALPLATFORM PIVOTALLY CONNECTED TO EACH SAID VERTICAL SUPPORT MEMBER AT APOINT APPROXIMATELY MIDWAY BETWEEN SAID ENLARGED PORTIONS, SAID PLATFORMCOMPRISING A PLURALITY OF RIBBED PLATFORM MEMBERS ADAPTED TO BECONNECTED TO EACH OTHER IN A TELESCOPING MANNER; AND A PAIR OF FOLDABLEDIAGONAL BRACES RESPECTIVELY CONNECTED FROM SAID PLATFORM TO THE TOPENLARGED PORTION OF ONE OF SAID VERTICAL SUPPORT MEMBERS, WHEREBY SAIDBRACES SERVE IN THEIR UNFOLDED POSITION TO BOTH STEADY SAID SCAFFOLDDEVICE AND REDUCE THE POSSIBILITY OF A USER ACCIDENTALLY STEPPING OFF OFTHE PLATFORM YET IN THEIR FOLDED POSITION PERMIT THE SCAFFOLD DEVICE TOBE COLLAPSED TO A RIGID AND SUBSTANTIALLY PLANAR CONFIGURATION FORSTORAGE OR FOR USE AS AN EXTENDED PLATFORM BETWEEN A PAIR OF LADDERS ORTHE LIKE.
